Aproveitando o tópico, meu caso é o seguinte:
Estou usando um notebook Positivo, onde instalei o Kubuntu 10.10, seguem alguns comandos:

No networking settings via KDE, tenho o SSID e senha configurados, ele ve as redes wifi (conforme ultimo comando logo acima) mas não estou conseguindo abrir nada na internet, muito menos fazer ping, pergunto, o que mais falta parta navegar.
Lembro que em versões anteriores de alguns linux tinha que con figurar resolv.conf (que não existe no Kubuntu10.10) mas de qualquer forma criei um e coloquei o OpenDns lá.
grato
